Troubleshooting Local Number Portability Problems
Resolving Local Number Portability Conflicts
Some conflicts can arise in the LNP processes.
illustrates the causes of conflicts and the
procedures that the Number Portability Administration Center (NPAC) service management system
(SMS) uses to resolve them.
If either the old or new service provider did not send a notification to the NPAC SMS, the NPAC SMS
notifies the service provider from which it did not receive a notification that it is expecting a notification.
If the NPAC SMS receives the missing notification, and both notifications indicate agreement among
the service providers, the process proceeds as normal.
The following list describes the actions that the NPAC SMS takes in different situations:
•
If the NPAC SMS does
not
receive a concurring notification from the
old
service provider, the
NPAC SMS logs the failure to respond and allows the new service provider to proceed with
activation when the new service provider due date is reached.
•
If the NPAC SMS does
not
receive a concurring notification from the
new
service provider, the
NPAC SMS logs the failure to respond, cancels the request, and notifies both service providers of
the cancellation.
•
If the service providers disagree as to who will provide service for the telephone number, the NPAC
SMS places the request in the “conflict” state and notifies both service providers of the conflict
status and the Status Change Cause Code.
–
The service providers then determine between them who will serve the customer using their
internal business processes.
–
When a resolution is reached, the NPAC SMS is notified by the new service provider and
removes the request from the conflict state.
Within the first 6 hours, only the old service provider can initiate “conflict off.” After 6 hours, either
service provider can remove the conflict status. The new service provider can alternatively request
cancellation of the Subscription Version.
